This Heatmiser UH8-RF Wireless Wiring Centre connects internal heating pipework by efficiently centralizing the management of your extensive underfloor system without the need for complex hardwiring. Specifically, it provides a highly durable and precise transfer of wireless signals from RF thermostats to operate up to 8 heating zones and manifold actuators. Furthermore, thanks to its completely wireless thermostat connection, you significantly speed up installation by replacing messy junction boxes and wall cables with a single, secure receiver panel.
Therefore, this Heatmiser UH8-RF Wireless Wiring Centre works perfectly for modern water-based underfloor heating (UFH) networks in larger homes, renovations, or commercial properties. Additionally, it easily handles demanding applications, seamlessly combining separate controls for your system boiler, circulation pump, and an optional domestic hot water cylinder from one compact location.
The unit features a robust construction with clear LED indicator lights that instantly display the operational status of your boiler, pump, and individual zones. Moreover, this highly efficient module is powered by 230V and works perfectly with dedicated wireless thermostats such as the neoAir v3 and Slimline-RF. As a result, this reliable build makes it fully dependable for long-term installations, guaranteeing safe operation under a maximum total load of 5A with IP20 protection.
Key Features & Benefits:
8-Zone Wireless Management: The system incorporates dedicated wireless channels for 8 independent heating zones, allowing connection for up to 6 actuators per zone. Consequently, you achieve precise room-by-room temperature management, completely eliminating thermostat cable clutter on site.
Selectable Radiator Zones: The software design allows you to configure specific zones to control traditional radiators instead of underfloor heating. Ultimately, this creates a highly customizable system where radiator zones trigger the boiler entirely without activating the UFH pump and mixing valve.
Full Boiler & Pump Control: The control centre smoothly transmits a Volt-Free enable signal to the boiler and a 230V supply to the manifold pump and UFH valve whenever any underfloor thermostat calls for heat. Importantly, this significantly increases automation and ensures fully safe hydraulic operation.
Seamless Wireless Integration: The unit features built-in capabilities to communicate with your RF thermostats and can even transmit the boiler signal wirelessly to an optional RF-Switch. For example, this allows you to create a completely wireless setup if the boiler is located far from the manifold.
Safe & Simple Installation: The module is supplied with the ability to be conveniently screwed to the wall or installed on a standard DIN rail. Besides that, the internal circuits and 230V outputs are effectively protected by a built-in 5A maximum load capacity within an IP20 rated enclosure.
